SUNG-HOLE FiTTING FOR CASKS OR BARRELS.

SPECIFICATION forming part of Letters Patent No. 668,186, dated February 19, 1901.

Application filed August l, 1899.

T all 11171/0771/ it 77cm/ concern:

Beit known that LWILLY HOMANN, manufacturer, a subject of the King of Prussia, German Emperor, residingat 14 Adersstrasse, Dusseldorf, Kingdom of Prussia, Germany, have invented new and useful Improvements inand Connected with Bong-Hole Fittings for Casks or Barrels, of which the following is a specification.

My invention relates to improvements in bung or tap hole fittings for casks or barrels which obviate the use of the ordinary cork plug and, consisting almost entirely of metal, can be easily and effectively cleaned and conveniently handled.

The invention provides an inexpensive but efficient device capable of ready removal whenever desired.

More particularly, my invention refers to that class of bung or tap hole fittings in which the valve in the interior of the fitting is actuated from outside by the screwing in of the tap.

My invention consists in certain improvements in the construction of such bung or tap hole iittings, which improvements are fully described hereinafter with reference to the accompanying drawings, in which- Figure l is a sectional elevation illustrating one way of carrying out my invention. Figs. 2 to 4 illu strate modifications in the construction of my invention.

Referring to the drawings, and particularly to Fig. l, the bushing G is provided with a bore of different diameters, the larger diameter being toward the outside of the barrel. Both portions of the bore are internally screwthreaded. lnto the screw-threadedlower and narrower portion of the bore a plug D, having its lower end externally screw-threaded in accordance with the lower portion of the bore in bushing G, the top end being externally plain, is screwed. The plug D is hollow, its bore extending downward to the conical extension d at the lower end of thelplug D, the lower portion being narrower and of square section and the outer portion being wider. Passages la extend from the square bore 'L' through the plug D, terminating above the conical extension d. The wider part of the bore of the plug D is screw-threaded, permitting the tap V to be screwed therein. The

tap,f1ttin g with a petticoat-like screw-threaded extension n,will simultaneously be screwed into the bushing G and the plug D. The step formed by the two different portions of the bore in the bushing G receives the packingring F. y

The device operates in the following manner: On screwing into the bung-hole :fitting the tap V the edge of the petticoat-like extension a will come to bear against the packing-ring F and the externally-screw-thrcaded ordinary end of the tap V will reach the bottom of the wider portion of the bore in the plug D, as illustrated in Fig. l. On now further screwing the tap V the plug D is forced to partake in the turning, the outer annulus n of the tap sim ultaneonsly tightening on the packing-ring F. The resilient material of the ring F permits of the plug D turning and advancing into the interior of the barrel, respectively, sufficient to uncover the passages 7c. The bung in this position will be open, permitting the exit of the contents of the barrel. On unscrewing the tap V the plug D will partake in the turning during the earlier part of same until the conical extension d comes to bear against the bushing G, when the passages la will again be covered. Thereupon the tap and its petticoat-like extension n will unscrew from the plug D and the bushing G, respectively, in the usual manner.

A modified construction of my invention is shown in Fig. 2, in which the bushing G is formed conically and closed at its bottom end. The corresponding conically-shaped plug D is fitted into the bushing G and is held in position by the ring o, surrounding it and screwed into the bushing. A packing-ring F may be interposed between this ring 0 and the step r, formed on the plug D. A horizontal passage p is provided in one side of the closed lower portion of the bushing G. The central bore of the plug D ends in a curved passage q, which terminates in the conical bottom portion of the plug, coinciding with the passage p in the bushing G. A stud E, screwed into the bushing G from inside the bore, projects into a horizontal groove A in the plug D, which extends over half the circumference of the latter. The bore immediately above the curved passage in the plug D may be of square section, as indicated by IOO t' in the drawings. On screwing in the usual externally screwthreaded tap V until its lower edge reaches the bottom of the top portion of the bore in the plug D the stud E and the conical bottom portion of the bushing G will prevent the advancement of the plug into the barrel, and on further screwing the tap to the extent of one hundred and eighty degrecs. the plug D will be turned from the position shown in Fig. 2, so that the mouth of the curved passage q coincides with the passage p in the bushing G. The extremities of the semicircular groove A in the plug may indicate the open and closed position of the plug D, the stud E preventing afurther turning at these two extreme positions.

In the further modified construction of the bung-hole fitting illustrated in Fig. 3 the bore in the plug D is eccentric,allowing the straight lower portion i of said bore to coincide with the passagep in the lower portion of the bushing G on turning the plug D into the proper position, the lower end of the plug being conical and fitting into a similarly conical and closed bottom end of the bushing G, as deu scribed with reference to Fig. 2. The operation of this bung-hole fitting coincides with that previously described, with the exception that the exit of the contents of the barrel takes place in a straight line through the passagep in the bushing G, the eccentric bore in the plug D, and the tap V.

The modified construction of the bung-hole tting shown in Fig. 4 varies from the constructions previously described in the following respects: An extension 0c of the bushing G Vcarries a horizontal pin'X', the latter having rigidly mounted on it a vspecial plug y, conically shaped and fitting into the conical lower portion of the bore in the plug D. A curved or bent passage y2 in the special plug y communicates at the upper end with the bore t' in Vthe plug D and terminates at the conical surface. The tapered lower end of the `plug D, projecting into the barrel, is provided with a passage i2, which on turning the plug D in the manner described with reference to the previous constructions to the required eXtent coincides with the amount of the bent passage y2 in the special plug y, thus permitting the exit of the contents of the Vessel.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A bung-hole fitting adapted to be actuated by means of the tap comprising in conibination a'hollow bushing G having the bottom end tapered inward and closed; an openingp in said tapered portion; a turnable plug D with conical bottom end tting into the bushing G; a ring o' for retaining the plug in position; a packing-ring F interposed between the aforesaid ring o' and the plug, a bore in the plug adapted to establish communication between the opening p in the bushing and the tap and means for limiting the turning of the plug in the bushing by screwing the tap, substantially as described and shown.

2. A bung-hole fitting adapted to be actuated by means of the tap, comprising in cornbination a hollow bushing G having the bottom end tapered inward and closed; an opening p in said tapered portion; a turnable plug D with conical bottom end fitting into the bushing G; a ring 0 for retaining the plugin position, a packing-ring F interposed between the aforesaid ringo and the plug; a bore in the plug adapted to establish communication between the opening p in the bushing and the tap; and means for limiting the turning of the plug` in the bushing consisting in a stud E projecting from the interior surface of the bushing into a groove A in the plug D; substantially as described and shown.

3. A bung-hole fitting adapted to be actuated by means of the tap, comprising incom bination a hollow bushing G having the bottom end tapered inward and closed; an openingp in said tapered portion, a turnable plug D with conical bottom end fitting into the bushing G; a ring o for retaining the position of the plug; apacking-ring F interposed between the aforesaid ring 0' and the plug; an eccentric bore in the plug adapted to establish communication between the opening p in the bushing and the tap in a straight line; andrmeans for limiting the turning of the plug in the bushing consisting in a stud E projecting from the interior surface of the bushing into a groove A in the plug D; substantially as described and shown.

In testimony whereof I have hereunto se my hand in presence of two subscribing wit* nesses.

WILLY IIOMANN.
